%description
This is a very simple type:

> data Exceptional x > = Failure String > | Success x

It's much like 'Maybe', except instead of 'Nothing', we have 'Failure String'.

A comparison could also be made to 'Either String'. I made this library because
I was dissatisfied with the 'Monad' instance for 'Either'. In this type, 'fail
= Failure'. It's rather simple.

Changes

[0.3.0.0] Fix erroneous behavior in 'foldExceptional' function added in version
0.2. This release actually does break (or rather fix) the 'foldExceptional'
function, so be careful.

[0.2.0.0] Add 'exceptional' function to encapsulate ordinary exceptions in the
'Exceptional' monad. Add folding functions.

This release does not actually break the API, however I was rather tired when I
chose the version number. This should be 0.1.6.

[0.1.5.0] Add 'exceptIO' function to encapsulate IO errors in the 'Exceptional'
monad.

[0.1.4.3] Fix bug where 'exceptional' won't compile on 'base < 4.8'.
Also move the changelog back to the description so it's more visible.

[0.1.4.2] Moved change log to a separate file so Hackage displays it correctly.

[0.1.4.1] Documentation enhancements/fixes.

[0.1.4.0] Added 'fromMaybe' and 'toMaybe' functions, and a link to the bug
tracker.

[0.1.3.0] Fixed a typo. 0.1.2.0 won't build. Also added definition of 'empty'
for 'Alternative'.

[0.1.2.0] Added 'fromEither' and 'toEither' functions.

[0.1.1.3] Hackage is terrible. Yet another formatting fix.

[0.1.1.2] Yet another formatting fix.

[0.1.1.1] Formatting fix to the haddock documentation.

[0.1.1.0] Add 'runExceptional' function.

[0.1.0.1] Minor documentation changes. No changes to the API.

[0.1.0.0] Initial version.
